“Build & Design:
Great. Audiofly chose to use very good materials for the AF45. They're available in four colors: Black, White and Black, Green Olive, and Brown.
Starting from the straight plug, it's very sturdy and well relieved. The housings, while are made of plastic, feel very sturdy too. They are lightweight but a bit on the large side.
As for the cable, it's a Y-cable and one...” --Zelda

Some things are just better in pairs. Think Mick and Keith, George and Ira, Jordan and Pippen... For a lush, kicking bottom-end with immaculate mid and high frequency detail, Audiofly teamed two technologies: dynamic driver with balanced armature driver. And it's seriously good.Hybrid Dual DriversHybrid configuration of dynamic and balanced armature drivers delivers a warm yet crisp...

“Before I get started, I’d like to thank the team at Audiofly and Billy from Noisy Motel for making this tour possible. I know that the AF140s have received some criticism so far which is always a risk during a tour, but I tend to agree with @djvkool's rating of the AF140s and honestly believe that the criticism from others is misplaced and a result of personal tastes (which we are all...” --Loquah

“Audiofly has made the most comfortable IEMs that I've placed in my ears. They are probably the easiest to insert as well. I was ready to plunk down the cash and go the custom route, but these have changed my mind. The manufacturer was kind enough to include Comply brand tips in their packaging, which certainly entirely alleviates feeling of having foreign bodies in my in my ears. I've easily...” --hardbop

The earphones were given about 40 hrs.
The AF56 are not just an improvement over the AF45 in design and comfort, but also, and mainly, in Sound. They offer a much bigger and very lively sound with better overall balance.
Not unlike the AF45 model, the bass is very dominating. But...” --Zelda

“If you want to read me ramble on more about haptics and finish quality, head to Ω image's review.
I know it is a year on and this earphone is no longer en vogue. However, I reviewed it. Take that world! ARggggh!
Why has it taken so long for me to get this on? Well, because I take a long time. Yes, even if the review is short. And I've sort of changed opinions on a...” --shigzeo

“
I am lost for words for 2 reasons, 1st: These in ears behave much more like over ears headphones in all the good ways.
2nd: these deserve to be much more popular than they are, I am simply shocked that there is not much more renowned!
I currently own the Shure SE535's as well as Sennheiser IE8 and have used and owned many of the 500 and under earphones, such as Monster Turbine Copper Pro...” --Tenor123

“
I love the full size grado HF2 and older grado's but these do not sound good to my ears. Strident and uneven. These were not lovingly crafted or dialed in. There was no 'man' behind the tuning of these and this is evident in the final product. I'd love to see grado come out with a smooth yet dynamic sounding iem similar to the HF2 but am not holding my breath, especially when I've found...” --thelostMIDrange
